This study introduces a novel analytical method for the determination of nitrobenzene (NB) and 1,3-dinitrobenzene (DNB) from an aqueous solution using high performance liquid chromatography (HPLC)and anthracite as adsorbent for pre-concentration. The method showed good linearity for determinationof NB and DNB concentrations in the range of 0.10–200 mg L-1 with regression coefficients better than0.9995. Limits of detections (LOD) were 0.010 and 0.055 mg L-1 for DNB and NB, respectively. Relativestandard deviations (RSD) for 0.50 mg L-1 and 150 mg L-1 were in the range of 2.0–3.8% for (DNB) and3.0–4.8% for (NB).
